ENERGY
BALANCE
December 2008
Definition:
The energy balance is an account in which
shows the complete set of relations of
equilibrium that accounts for streams Physical by
which energy is produced, exchanged with the
outside world, is transformed, consumed, and so
on.; All this in a calculated common unit within a
given country and for a specified period (usually
one year).
ADVANTAGES AND
DISADVANTAGES:
It is important to bear in mind both the
advantages and limitations of the balance
sheet. The balance sheet is a tool that
facilitates global energy planning, but
considered alongside other elements of
the economic system.
That is, taken in isolation the balance
sheet gives a picture of the relationship of
physical energy system in a particular
historical period. Shows such as the
energy is produced, exported or imported,
is transformed and consumed by
economic sectors.

It lets calculate certain relationships of efficiency
and make a diagnosis of the energy situation of
a country, region or continent since. However, it
is through their relationship with other socioeconomic variables that the balance becomes a
planning tool.
In this sense, the existence of the energy balance is a necessary
condition for energy planning.

The energy balances in
terms of final energy
(EBFE), has the limitation
of
not
making
an
assessment
of
energy
reserves and do not reach
the stage of useful energy
(EBUE).
On the other hand, for
developing countries, given
the importance of the rural
sector and the sources of
"non-commercial" energy is
essential to include in the
balance
sheet
such
consumption in order to
meet the energy structure of
the rural sector, its problems
and implications on the
national economy.
FUNDAMENTAL OBJECTIVES OF
THE ENERGY BALANCE:
 To assess the dynamics of the energy system in line with the
economy of
each country, identifying the major energy-economic relationships between the
different sectors of the national economy.
 Serve as a tool for energy planning.
 Knowing in detail the structure of the national energy sector.
 Determine for each source of energy uses competitive and non-competitive
to push wherever possible replacement processes.
 Create the appropriate bases leading
systematization of information energy.
to
the
improvement
and
 Be used to allow the projection of energy and its prospects in the short and
long term.
OVERVIEW:
The energy balance in terms of final energy
(BEEF) of OLADE is presented in matrix form,
and is composed of columns, which represent
energy sources (primary and secondary), and by
the rows that represent the activities, namely the
origins and destinations or consumption of
energy.
The basic components of the balance sheet are:
-ENERGY SOURCES
Primary Energy
Secondary Energy
- TOTAL SUPPLY
- PROCESSING CENTERS
- FINAL CONSUMPTIO

- FINAL
CONSUMPTIO
PRIMARY
ENERGY .-
The term primary energy to the various
sources of energy as obtained in the wild,
either in direct form as in the case of
hydropower and solar, wood and other fuels
plant, or after a process of extracting the
oil, coal, geoenergy, and so on.
SECONDARY
ENERGY .-
It's called secondary energy to the various
energy products that come from different
centers for processing and whose fate are
the various sectors of consumption and / or
other processing plants.
TOTAL
SUPPLY.- :
It is the total net availability of energy to meet
the energy needs of a country's economy. The
total supply of energy is then, the amount of
energy primary and secondary available to meet
the energy needs of a country, both in the
processes of transformation, and in the end.
The "total supply" is calculated by the equation:
Total bid = Production (+) Import (-) Export (+ -) Change in
inventories (-) Not exploited
CENTERS OF
TRANSFORMATION :
It refers to the energy that comes
to be amended in special
processor
called
processing
centers, these centers produce
chemical or physical changes of
an energy source to another or
others, looking this way better
utilization
of
energy.
CONTINUED……
The processing plants are considered:
Refinery:
Center where the oil is
processed
into
products. In refineries
basically crude oil is
separated
into
its
various components.
Power
Plants
(Public
and
self
producers):
These
processing plants are
built according to the
case, for hydroelectric
power, thermal power
conventional
steam
turbines, gas turbines
and
internal
combustion
engines,
power
plants
and
geothermoelectrics.
Gas Treatment Center:
In the treatment plants and
associated natural gas is
processed with the main
purpose
of
recovering
liquid
hydrocarbons
compounds,
such
as
naphta and gasoline, pure
hydrocarbons
such
as
butane, propane, ethane or
mixture of them and non energy, such as carbon,
through a process of
physical separation of the
components of the gas.
OWN
CONSUMPTION :
This is one of four possible routes for
the total supply. The consumption of
energy is the part of primary and
secondary energy that the industry
uses to function.
LOSSES:
Are those that occur during the activities
undertaken since the energy is produced up to
the final consumer. Among other things, include
the loss of extraction, storage, transportation,
transmission, distribution, etc..
Loss is different from untapped because while
the latter could be exploited fully if conditions
were given, the first can only be reduced through
conservation.
STATISTICAL
ADJUSTMENT:
This line serves mainly in some cases to replenish the differences
produced by the conversion of different sources, from their original
units of measure until the units are compatible for the development of
the balances.
The adjustment should be no higher than 5% of
the total offered.
FINAL
CONSUMPTION :
Transport Sector:
Industrial Sector:
The end of the carriage of a
country is the total amount of
fuel required to move the
vehicle fleet. The modes of
transport can be:
An industry is a classified as
such in the "great division 3" of
the International System of
Industrial Uniform Classification.
ISIC.
The
final
consumption of the industrial
sector is constituted by any
energy source used in the
processes that are carried out
within the limits of the
establishment, in which certain
raw materials are processed
into finished products.
a) highways,
b) Railway,
c) Air,
d) River, and
e) Maritime.
FINAL
CONSUMPTION :
Residential Sector:
The end of this industry is
that for urban and rural
households in a country. A
home is what the census
defines as such and there are
so many homes as censuses
and mechanisms derived
identified.
Commercial sector, Services
and Public:
This consumption corresponds
to
Retail
establishments
belonging
to
wholesalers,
retailers, restaurants, hotels
etc.. The final consumption
sector is the establishment of
everything listed above if it
occurs within the building where
it is located. This excludes the
consumption of vehicles.
FINAL
CONSUMPTION :
Agro Industry,
and Mining:
Construction
others:
Fishing
Sector
and
This sector consists of two subsectors: construction and other
sectors.
The information sector is a
defined
as
agriculture,
hunting,
forestry,
sawing
wood, fishing, extraction of
minerals and metals.
- Construction: New buildings and
renovation of old buildings, new industrial
establishments, civil works, such as
bridges, dams, tunnels.
-
Other sectors, it is for any consumer of
energy sources not specified in the sectors
identified

energy goods.
Total Final Consumption:
It is all the energy that is
delivered to the consuming
sectors, both for energy uses,
as no energy. The amount of

total.
ADOPTED
UNIT:
Power supplies and products used for their generation are
measured by their mass or weight, its volume, its contents heat,
its energy and its ability to perform work. The original units in
which they are measured normally fuels and electricity are
extremely disparate (tons, barrels, cubic meters, calories,
kilowatt hours, etc.)..
ADOPTED
UNIT:
Aiming to close the global balance of
power and enable the analysis of
comparative data and consideration of
the energy structures of a country,
subregion or region, triggering the
homogenization of the physical units of
measurement of the energy using a
different unit Thermal or caloric common.
Ecuador has adopted Equivalent Oil Tonnes (EOT) as a common unit
for expressing energy balances.
